Hydrangeas: Show stopping Blooms with Easy Care

Hydrangeas are beloved garden shrubs known for their massive, colorful flower heads. With a little know-how, you can keep your hydrangeas thriving and blooming season after season.

Hydrangea Care Basics

  • Light: Most hydrangeas prefer morning sun with afternoon shade. Some varieties, like panicle hydrangeas, can tolerate full sun.
  • Water: Consistent watering is key. Aim to keep the soil evenly moist, but not soggy. Water deeply when the top inch of soil feels dry.
  • Soil: Well-drained, acidic soil is ideal. Amend clay soil with compost or other organic matter.
  • Mulch: Apply a 2-3 inch layer of mulch around the base of the plant to retain moisture, regulate soil temperature, and suppress weeds.
  • Fertilizer: Fertilize lightly in early spring with a fertilizer formulated for acid-loving plant, like Holly Tone. Avoid over-fertilizing (all fertilizers will have different dose sizes on the packaging), as this can reduce flowering.

Troubleshooting: Why Are My Hydrangeas Not Blooming?

  • Incorrect Pruning: Bigleaf hydrangeas (the most common type) set flower buds on old wood. Pruning in fall or winter can remove these buds. Prune right after flowering or in late winter before new growth appears.
  • Lack of Sun: Insufficient light can prevent blooms. Ensure your hydrangeas receive at least 3 hours of morning sun.
  • Watering Issues: Both underwatering and overwatering can hinder flowering.
  • Nutrient Deficiency: A lack of essential nutrients, particularly phosphorus, can affect flower production. Use a fertilizer formulated for acid-loving plants like Holly Tone.
  • Soil pH: Hydrangeas prefer acidic soil (pH 6.0-6.5). If your soil is too alkaline, the flowers may turn green or not bloom at all.

Bonus Tip: You can influence the flower color of some hydrangea varieties! Adding aluminum sulfate to the soil can intensify blue blooms, while adding lime can promote pink or purple flowers.

By following these tips and addressing any potential issues, you can help your hydrangeas flourish and fill your garden with vibrant blooms for years to come.
